Back-up Plastic Key lost its Mind


2015 R1200GSA with keyless ignition. Coming up on 1 year of service and 23,000 miles.

I wanted to use my back-up plastic key tonight to get my odo mileage for the contest and........nothing happened! No, that's not entirely correct. There was a flashing red light on the right side of the panel when I pushed the keyless ignition button.

I seem to recall that the key worked in the past. I also tried the key in the 'secret spot' to no avail. Have others had this problem?
